there are 12 atoms of mg in the following equations
<h3><u>Answer;</u></h3>
Element
<h3><u>Explanation;</u></h3>
Oxygen is an element and not a compound.
Elements are substances that can't be split into simpler substances by chemical means. They include, hydrogen, oxygen, sodium, etc.
Compounds are substances that are made up of two or more elements e.g. water is a compound, since it is made up of oxygen and hydrogen element. Compounds unlike elements can be split into simpler substances by chemical means.
The correct manipulation of the ideal gas equation as shown here is (PV)/R=nT.
<h3>
What is the ideal gas law?</h3>
According to the ideal gas law; PV = nRT. Now, this law applies to gases at high temperature and low pressure.
Given this fact, we know that the correct manipulation of the ideal gas equation as shown here is (PV)/R=nT.

Answer: 67.2 liters
Explanation: lucky guess and I got it right on a test.
To determine the heat required to raise a body's termperature by a certain number of degrees C, we use the equation,
H = mcpdT
where m is mass, cp is specific heat, and dT is the temperature difference. Substituting the known values,
H = (30.0 g)(0.90 J/gC)(75 - 25)
H = 1350 J
Thus, there is a need for 1350 J of heat for the process.
